se/backs, lot standards, and street standards. She explained the preliminary plat is proposing to develop 16 single-family lots and 26 single unit detached townhome units for a net density of 2.75 units per acre. Single-family lots are permitted within the R-1 District and townhome units arc permitted through processing a PUD. Associate Planner Wald explained the preliminary plat is proposing to gain access from Potassium Street and Radium Street. The subdivision is complying with City Code by connecting to Radium Street, which is located within an existing residential neighborhood. The preliminary plat is also proposing a private street within the detached townhouse portion of the development. City (;ode states private streets that exceed 300 feet in length are required to be 32 feet in width. In order to provide for as much green space as possible from the private street to thc existing neighborhood, the preliminary plat is proposing a 28-foot wide street. The proposed private street deviation will need to be addressed as part of the acceptance of the PUD rezoning. 'Ibc cul-de-sac servicing the single-family lots exceeds 600 feet in length by 49 feet; this deviation will need to be approved as part of the acceptance of the PUD rezoning. Associak: Planner Wald explained along the northern plat boundary line, the subject property is located next to single family lots that are located outside of the Metropolitan Urban Service Area (MUSA) and therefore the plat will be subject to density transitioning. City Code allows the City to determine the proper buffer level for PUD developments. The plat is providing a 29 - 30 foot bu ITer area adjacent to the existing residential development. The buffer area will contain a berm and extensive vegetation. She advised City Code requires 20% public open space or 50% private open space lbr developments that are processed through a PUD. The development is proposing 50.2% open space. It should be noted that only 50% credit was given to the wetlands, which is consistent with credit given when calculating public open space area. She indicated Bolton and Monk completed a traffic generation analysis study for the proposed residential development. 'l'he study shows that the level of service on the existing streets and intersections will not be negatively impacted due to the proposed development. Bolton and Menk made the following recommendations: · Place a stop sign at the northbound approach of Radium Street and 157th Lane Place a stop sign at the southbound approach of Potassium Street and Old CSAH 5 I lpgrade Potassium Street to provide a paved surface and adequate width [] [Jpgradc width and roadway surface of Old CSAH 5 Associate Planner Wald indicated the landscaping plan is acceptable. The grading and drainage plan will need to be revised in accordance with the staff review letter. She explained the property o_mlains several wetlands. The developer has agreed to establish a "No Mow" zone along the wetlands. This will help future residents know where they need to stop establishing a manicured lawn. Stal'l' is also requesting that the developer plant appropriate seeding specifications within a portion of the no mow zone to further establish and protect the wetland areas. She indicated the Park Commission reviewed the proposed plat for park dedication and trail requirements at their April l zl, 2005 meeting. The Park Commission recommended that park dedication and trail fees be satisfied through a cash payment. The preliminary plat is providing a bituminous trail along (iounty Road 5 and is providing a pedestrian connection within the plat from Quicksilver Circle City Council/May 10, 2005 Page 14 of 31
